Best movie to see what your HT AUDIO will do.

I recently watched U571 in blu ray and have to say, wow! I had't seen this movie since I made several substantial upgrades and it knocked me out. It struck me because I've been watching a lot of movies recently that are full of sci-fi type effects,The Avengers, Iron Man 1,2,3 Star Trek, etc. Hey, I like action movies. The new Superman audio was very good and the newest Die Hard audio was good as well. Maybe U571 struck me because it was more potentially real sounds versus a planet exploding, etc.

What movie do you put in, old or new that makes you still say WOW! about the audio portion of the movie?
